I know access path is the path chosen by the program to
retrieve data.
It can be of keyed access path or arrival sequence.
*IMMED- *IMMED description says access path is updated each time
record is added or deleted from a member. - What is updating
here?
*REBLD - The access path is completely rebuilt each time a file
member is opened. The access path is maintained until the
member is
closed, then the access path is deleted. - I am not able to
understand this completely.

Could anyone explain these more clearly?
